I odn't know why you are all worrying about oil running out.... I believe the scare mongering and government warnings and therefore died of AIDS with 75% of the worlds population about ten years ago. Which was lucky as it saved me from getting CJD and E-bola virus. Fortunately the hole in the ozone layer pumps in enough UV to render most bacteria harmless.
Balls to the lot of it. We are pretty big headed, destroy the earth? Vesuvius pumped out as much polution in a week than we have in the 1000 odd years since when it took out pompeii. The planet survived that.
Anyway, the world will be a more peaceful place in a hundred years due to all the plasticizer in the water table (it's a chemical used by oil companies when producing plastics) it's an oestrogen analogue so we are all becoming more female, it's happening to fish already.
So the end of the world won't be due to virus, weather or economic collapse, it'll happen during the Eastenders omnibus....... we'll get invaded by martians and no-one will be paying attention.
Seriously, If you worry about everything you hear, then it doesn't actually leave you any time to do anything about it.
